## **3. Configure Hadoop, Spark, Hive to use MinIO**

After successful installation navigate to the Ambari UI `http://<ambari-server>:8080/` and login using the default credentials: [**_username: admin, password: admin_**]

 *  **OkHttp now supports TLS 1.3.** This requires either Conscrypt or Java 11+.

 *  **Proxy authenticators are now asked for preemptive authentication.** OkHttp will now request
    authentication credentials before creating TLS tunnels through HTTP proxies (HTTP `CONNECT`).
    Authenticators should identify preemptive authentications by the presence of a challenge whose
    scheme is "OkHttp-Preemptive".

#### Credential provider

- The AWS credential provider can now obtain ECR credentials even without the AWS cloud provider or being on an EC2 instance. Additionally, AWS credential provider caching has been improved to honor the ECR credential timeout. ([#75587](https://github.com/kubernetes/kubernetes/pull/75587), [@tiffanyfay](https://github.com/tiffanyfay))

   * Confirm that we don't send the Proxy-Authorization header from the request to the proxy server.
   * We used to have that behavior but it is problematic because unrelated requests end up sharing
   * credentials. Worse, that approach leaks proxy credentials to the origin server.
